Simulation support of freight delivery schedule in urban areas

Abstract

Determining of the delivery schedule in urban areas requires consideration of points of view of various players, such as suppliers, customers, but also (indirectly) inhabitants of city. Taking into account these interests in the optimization model is necessary to ensure the sustainable transportation of cargo in cities. Moreover, the solution of this task is a complex process and requires to use of appropriate methods. The problem taken in the article belongs to a class of Vehicle Routing Problems (VRP), more specifically Rich VRP. For its solution metaheuristic method was applied. In this article, the verification of the part of delivery plan due to the duration of the route was made. A description of the problem and isolated fragment of solutions for simulation verification were presented. The article presents the simulation results of presented problem in case of the transport time.
